Since you ask for real ideas and suggestions on how to help the environment, I thought would try to really think of all the things it takesto run a fine store and business like Mac's in a more green way.  I also have enjoyed lots of Frosters and the good service and products at Mac's. I hope these ideas help.Install LED lights in all your parking lots.Construct your stores and distribution centers with low-emitting materials including: adhesives and sealants, paints and coatings, floor systems, composite wood and laminate adhesives.Use Energy efficient commercial equipment.Use High Efficiency HVAC . The heating cooling and ventilating of your stores, centers and offices are likely responsible for more than half of their energy use and costs. (Online Guide to Energy-Efficient Commercial Equipment http://www.aceee.org/ogeece/ch3_index.htm)Use remote condensing units for refrigeration and ice making equipment.Use day lighting and controls for high efficiency lighting like compact flourescent light bulbs, halogen light bulbs, or LED light bulbs.Use LED lights for interior and exterior signs.Install low flow water fixtures.Use building and decor materials made from sustainable sourcesUse paper napkins that are made from 100 percent recycled materials made with a minimum of 60 percent post consumer recyclables.Have recycle bins to recycle wrappers, napkins, cups and other packaging, cans and bottles.Switch the materials used for the manufacturing of your cutlery and plastic drinking cups from polystyrene to polypropylene. This change will result in an annual resin savings of hundreds of thousands of pounds and will save many thousands of barrels of oil.Use energy efficient windows with high R value for winter to keep heat in and for summer to keep heat out.Use hybrid electric or natural gas or propane or hydrogen fuel cell or biofuel biodiesel vehicles (http://www.biofuelcanada.ca/)Increase your Green Marketing.(82% of Firms Plan to Boost Green Marketing Spending         http://www.environmentalleader.com/2010/01/07/82-of-firms-plan-to-boost-green-marketing-spending/  ) Promote coupons for green products and services in store and in the community.Become LEED certified Silver, Gold or Platinum and advertise it.
